Specification of Letters Patent.

Patented July 18, 1922.

Application filed October 10, 1917'. Serial No. 195,713.

To all whom it may concern: I

Be it known that I, FRANK D. lt ilALTBY, citizen of the United States,-residing at Battle Creek, in the county ofvOalhoun and State ofMichigan, have invented certain new and useful Improvements in Primingand Decarbonizing Devices for Internal-Combustion Engines, of which thefollowing is a specification.

This invention relates to improvements in priming and decarbonizingdevices for internal combustion engines.

The main objects of this-invention are: k

First, to provide an improved priming and decarbonizing device forinternal combustion engines which may be quickly and easily operated toprime the engine or to ad'- just the device to conduct water to theengine for decarbonizing purposes or to supply the desired humidity.

Second, to provide an improved device of the class described which maybe applied to motor vehicle engines so as to be operated from the dashof the vehicle.

Third, to provide a device'of the class described which may also-beadjusted to admit an auxiliary supply of air.

Further objects, and objects relating to structural details, willdefinitely appear from the detailed description to follow.

l accomplish the objects of my invention by the devices and meansdescribed in the following specification. The invention is clearlydefined and pointed out in the claims.

A structure which is a preferred embodi ment of my invention is clearlyillustrated in the accompanying drawing forming a part of thisspecification, in which:

Fig. I is a detail side view of an engine equipped with my improvements,the engine, carbureter and certain other parts being shown mainly inconventional form.

Fig. 11 is detail transverse section on a line corresponding to line 2-2of Fig. I.

Fig. III is an enlarged transverse section of the pump nozzle.

Fig. TV is a detail of the valve and plunger actuating rod partially insection, on a line corresponding to line of Fig. V. w

Fig. V is a detail plan view of the control means taken on a linecorresponding to line 5-5 of Fig. TV.

Fig. V I is a transverse section through the water and air valve onlinecorresponding to line 6-6 of Fig. V.

Fig. VII is a front view of the dash plate, the plunger operating rodbeing shown in section. a

In the drawing, similar reference characters refer to similar partsthroughout: the several views, and the sectional views are takenlookingin the direction of thelittle arrows at the ends of the section lines.

eferring to the drawing, 1 represents an engine havinga manifoldorintake passage E2 formed in the body thereof as is the practics incertaintypes of engine. 3 represents the carburetor and 4 the vacuumfeed tank. The outer manifold wall is provided with openings 5 either ofwhich is adapted tore celve connecting plug 6 for the vacuum tankconnection 7. The second opening 5 is ordinarily closed by a plug 8. Aplurality of these connections are ordinarily provided so that thevacuum tank connection maybe made as most convenient.

My improved priming and. decarbonizing device is adapted to be connectedwith the manifold through one of these openings although it will beunderstood-that a special opening could be tapped into the manifoldwall. These parts are shown mainly in conventional form in order to moreclearly show theadaptation of my improvements.

provide a priming pump, designated generally by the numeral 9, having alaterally projecting delivery arm 11 threaded so that it may be engagedin the threaded opening 5 of the manifold after the vacuum tanlr 6 hasbeen removed.

The passage arm 11 is provided with a pair of passages 39 and 40 openinginto the manifold and terminating at their outer ends in laterallydirected portions through the nipples 4 1 and 42 respectively. Thepassage 40 is connected to the vacuum feed tank 4: by means of the pipe7, the connection for this pipe being made to the nipple {C2 instead ofthe coupling 6 as shown in Fig. II.

The passage 39 is connected to a valve casing 43 by means of the pipela. The valve casing having a discharge port L5 therein with which thispipe as communicates T he valve casing is also provided with a port 46connected by the pipe to the water cir culation pipe 48. The pipe 4;?might be connected to any other suitable sourceof water supply. Thevalve casing d8 has an inlet port 49. The valve 50 is so designed thatit may be adjusted to connect the ports 43:5 and 46 of the valve casingand thus connect the water supply with the passage 39 through theconnections described so that water may be delivered to the manifold fordeca-rbonizing purposes, or to furnish desired humidity, or the valvemay be adjusted to connect the passage 45 with the air inlet 49 of thevalve casing and thus admit an auxiliary supply of air through thepassage 39.

The stem 51 of the valve 50 is disposed through a face plate 52 and hasa finger piece 53 and an index 5st, the face plate being provided withsuitable indicia indicating the air and water positions of the valve.The valve casing and face plate are arranged on opposite sides of thedash or instrument board 55 andare secured by the clamping member 56which is arranged through the face plate and threaded into an opening inthe bracket 57 of the valve casing. The plunger actuating rod 36 isarranged through the clamping member and is slidably supported thereby.

With the parts thus arranged, it is only necessary in attaching myimprovements to remove the connecting plug 6, where the manifold isprovided with such a connection, and if not so provided it is onlynecessary to tap the manifold to receive the delivery and supporting arm11. The arm 11 is threaded into the hole and secured by means of thelock nut 20. The pump is thus supported by this single member. Byarranging the parts, as I have indicated, upon the dash or instrumentboard, it is only necessary to bore a couple of holes in the same toreceive the valve and the clamping member. This clamping member servesas an effective securing means for both the face plate and the valve anda support for the plunger actuating rod. It will thus be seen that theparts are very easily and quickly assembled on structures not especiallydesigned, therefor. In practice my improvements are operated as follows:in priming the engine, the plunger is actuated to draw a quantity offuel into the pump cylinder through the pipe 25, which is connected forconvenience to the lower end of the fuel reservoir, or any other fuelsupply. The return of the plunger to its initial position forces thefuel through the nozzle into the manifold, it being atomized and brokenup so that an explosive mixture is at once drawn into the cylinder onthe first intake stroke of the piston. When it is desired to admit anauxiliary supply of air, the valve 50 is turned to admit air through theport 49 whence it passes through the conduit 4% to the manifold. If itis desired to admit water, the valve is turned to open the port 46,which is connected by the pipe 47 to the circulation pipe 48 or othersuitable water supply.

I have illustrated and described my improvements in one form in which Ihave embodied the same for the market. I have not attempted to describecertain improvements or adaptations which might be desirable for otherforms of engines as I believe the disclosure made will enable thoseskilled in the art to which my invention relates to adapt or embody thesame as may be re quired to meet various structural conditions andpractice.

Having thus described my invention, what I claim as new and desire tosecure by Let ters Patent is:
